Nico Hoerner vs Nick Madrigal
Second-base is the only position that neither team has a guy really slated to play for sure. The White Sox might use Leury Garcia at first but the plan is for Nick Madrigal to take over in the long term. The Cubs are in a similar position. Addison Russell is no longer there and Javier Baez is now the full-time shortstop so that leaves that spot a little bit unknown.
The Cubs are hoping that Nico Hoerner is going to be the guy who snags that position in the long term. He is a great young player that has worked his way up from the Minor Leagues to get to the Cubs. The thing that Hoerner has on Madrigal right now is a bit of experience. He played in 20 games for the Chicago Cubs last season and was pretty good. He managed to hit .282 with 3 home runs, 17 RBIs, and 13 runs scored in those 20 games.
Hoerner was taken 24th overall in the first round of the 2018 MLB Draft. In the same draft, the White Sox took Madrigal with the fourth overall pick. Hoerner might know a little bit more about what to expect at the MLB level now but in a situation like this, you have to go with the player who has the higher ceiling.
